News has come that Apple plans to begin accepting preorders for the long awaited iPhone 5 on announcement day. iMore, the first source to announce September 12th as the official reveal date has released further evidence to confirm the preorder date. Unfortunately, typical of all previous iPhone releases, preorders will be available first for customers in the US and a couple other countries while the rest of the world will have to wait for the second wave of shipments coming sometime in October.
If I were you, I'd ready my credit card the moment the Apple Online Store starts accepting preorders. The iPhone 4S preorders were sold out in literally hours and who knows how many more Apple-hungry customers are waiting this time around. Best of luck to all you!
